1. Species vary over time
2. The fossil and the living species will have some similarities and some differences
Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery.
Dehydration synthesis is a process where formation of a water molecule takes place while joining two molecules. Hydrolysis refers to a chemical reaction where breakdown of water molecule takes place. Thus, both the processes are opposite to each other but are related to each other while harnessing energy from the food. During dehydration synthesis the food molecule is formed with extraction of water from the food while during hydrolysis digestion of food particle takes place and water molecule is used in the process.
Answer:
The genotype of the original parents is pp PP
Explanation:
Let “P” represents the purple color allele of the flower of pea plant
and “p” represents the white color allele of the flower of pea plant
Genotype of homozygous purple flowered pea plant is represented by "PP"
Genotype of homozygous white flowered pea plant is represented by "pp"
a) First generation cross between a homozygous purple flowered pea plant and a homozygous white flowered pea plant
P P
p Pp Pp
p Pp Pp
All the offspring are heterozygous purple flowered pea plants
b) In second generation cross is taking place between two heterozygous purple flowered pea plants with genotype "Pp"
P p
P PP Pp
p Pp pp
Out of four offspring , one is white while rest three are purple flowered pea plant.
Hence, the genotype of the original parents is pp PP
Answer:
There are techniques to test that if an individual is practicing proper aseptic techniques to ensuring the growth of the pure bacterial colonies. The one of the experimental way to test is as follows:
Leave a Petri plate poured with media at lab, leave it for some time in open. Then incubation of the petri plate for 24 hours.
If bacteria colonies found on the plate, then the aseptic techniques that is following are not proper.
